INVENTOR Patented Sept. 29, 1936 UNITED STATES FATENT OFFIQE 11 Claims.

This invention relates to stencil sheets of the kind suitable for use in connection with duplicating machines or the like and in which the stencils or matter to be reproduced are cut or produced by a typewriting machine or other suitable means.

As is well known in the art, stencil sheets suitable for use in connection with duplicating machines are made of light flimsy paper easily rumpled, creased or otherwise injured during the handling thereof and when transported or stowed away for use.

In order to facilitate proper duplication, to avoid waste, and to provide for the repeated use of the same sheet, it is essential that the stencil sheet be at all times preserved and maintained in a smooth state, unimpaired by rurnples, creases and tears.

To this end, an object of my present invention 2o is to provide a folder or envelope by means of which to preserve and protect the stencil sheet both before and after using the same. Another object is to achieve this end in a simple, practical and efficient way, and in such manner as to .5 make it easy and convenient to stencilize or type the stencil sheet with the aid of a backing sheet arranged to form an integral part of the folder itself and which during the typing operation forms a support in the usual way for the stencil sheet.

A further object of my invention is to provide for the stencil sheet a protective folder of the character described which is made with a recording surface or space adapted to exhibit either a notation place thereon identifying the stencilized stencil sheet, or a copy of the address, circular, or of any print or imprint written, typed or drawn over the stencilized stencil sheet which is contained in the folder.

A further object of my invention is to provide the protective folder with an interleaved portion which performs the function of a heading or collar for holding the stencil sheet in a smooth spread-out condition between the two integrally connected sides of the folder. This heading portion, integral with the folder, is detachable therefrom along a line in order to provide for the use of the stencil sheet in connection with a duplicating machine. After having been detached,

the heading portion is, at will, replaceable in its interleaving position, suitable means in the form of an integral interlocking flap being provided for detachably securing the same in such position firmly to the folder.

With the foregoing and other objects in View,

(Cl. Ll1-3.5)

the invention consists of the novel construction, combination and arrangement of parts as hereinafter more fully described, and illustrated in the accompanying drawing, wherein is shown one practical example of the invention.

in the drawing, wherein like reference characters denote corresponding parts throughout the several views:-

Figure 1 represents a plan view of the folder in spread-out or extended condition, looking at 1U the inner face thereof, with a portion of the stencil sheet broken away;

Fig. 2 is a similar view, but showing the heading portion and accompanying stencil sheet folded inwardly upon the backing sheet, ready 15 for insertion in a typewriter;

Fig. 3 is a fragmentary plan view of the protective folder in folded condition, showing the exterior of the backing sheet or side, with the interlocking flap of the fronting or counter side 20 engaged with the backing sheet;

Fig. 4 is a view similar to that of Fig. 3, but showing the exterior of the fronting or counter side;

Fig. 5 is a cross section taken on the line 5-5 25 of Fig. 4; and

Fig. 6 is a cross section taken on the line 6--6 of Fig. 3.

In describing my invention, the terms and expressions which I use are employed as terms of 30 description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described or portions thereof.

The body of my folder may consist of any 35 flexible paper or similar material suitable for use as a backing and protective covering for the soft flimsy' sheet Iil of stencil paper, and in the illustrated exemplification, the body of the folder is represented as comprising a backing sheet or side 40 II and a fronting sheet or side I2. These two sheets or sides, II and I2, may be of the same size and they are made in one piece, their integral connection being at the foot end of the folder along a transverse fold or turn line I3 45 which acts as a hinge to provide for opening and closing movement of the folder.

Integrally associated with the head end of the backing sheet II is a heading or collar I4 which is movable on a perforated turn or fold line I5. 50 To this heading or collar, the stencil sheet I0 is attached at its head end by any suitable means, as for instance by paste or gum; and the combined length of these two parts, when so united, is approximately equal to the length of the back- 55 ing sheet ll between the turn or hinge lines I3 and I5, and in this connection it may be pointed out that when the heading lli is moved into a position to overlie the inner face of the backing sheet ll with the accompanying stencil sheet superposed and smoothly spread out as shown in Fig. 2, the free inner end l@ of the stencil sheet should come slightly short of the turn or hinge line i3 so as not to be rurnpled or creased during the opening and closing movement of the folder.

Integrally associated with the head end of the fronting sheet or side i2, is a flap part Il which is movable on a transversely extending turn or fold line i3 the function of which is that of a hinge. In the present exemplification, this flap part Il is represented as being formed with three spaced-apart projections or tongues I9, 2@ and 2 l. When the folder is closed, that is to say when the fronting sheet l2 is superposed upon the stencil sheet 'IU and its heading lll, or vice versa, when the backing sheet I l with the parts lli and l!) properly overlying the inner face thereof, is superposed upon the fronting sheet i2, the flap part Il may be moved across the head or perforated edge of the heading Ml and thence be applied flatwise alongside the outer face of the backing sheet l l, as shown in Fig. 3.

Means may be provided whereby to detachably secure the flap part ll' to the backing sheet H and also to the heading lli when the folder is in the folded condition illustrated in Fig. 3. In the present embodiment, the means for this purpose consists in providing the backing sheet l l and the heading lil with corresponding slots or openings 22, 22, 23, 23 and 24, 2Q, which corresponding openings are shaped and spaced for receiving therethrough the respective tongues is, 2Q, and 2l of the flap part ll. As illustrated in Figs. 3 and 5 the tongues are passed inwardly through their corresponding slots so that their free inner end portions can lie fiatwise between the adjacent faces of the heading and fronting sheet whereby firmly and yet detachably to secure the backing sheet, the fronting sheet and the interleaving heading together at the head end of the folder.

As illustrated in Fig. l, the inner face of the backing sheet may be provided with any suitable lining or marking as E5, or 26, or other figures or scales, designed to indicate to the typist where and how the stencil sheet should be cut Yto produce the desired stencilized sheet for duplicating purposes.

The outer face of the fronting sheet l2 affords a surface 2 Whereon may be written or typed any suitable notation for identifying the stencilized stencil sheet within the folder; and, When desired, a copy of the circular or of any print or imprint, produced from the stencil within the folder, or any written or typed identification thereof, may be pasted upon the surface or space 2l. With this arrangement for quickly identifying the stencilized sheet contained within the folder, much valuable time and labor can be saved, particularly in an oice or place of business where hundreds and perhaps thousands of stencilized stencil sheets have been prepared. The heading or cover i4 to which the stencil sheet is attached is provided with spaced keyhole slots 28 or other openings suitably shaped for use in applying the heading to the carrier of the duplicating machine in the usual way. The flap part ll and fronting sheet I2 adjacent the hinge line i8, and the backing sheet Il adjacent the hinge line l5 are also preferably provided with keyhole slots 29, 29', and 30, respectively, which slots are positioned so that when the folder is closed and the flap part interlocked with the backing sheet and heading, the keyhole slots 29, 28, 3E), and 2S will be in registration transversely of the folder, so that the folder, if desired, may be hung from suitable hooks, nails or the like, which are received in the registered slots.

From the foregoing description, taken in connection with the accompanying drawing, it will be understood that the backing sheet, heading for the stencil paper, fronting sheet and flap part may all be produced in one piece in which are provided the turn or hinge lines I3, i8 and I5, of which the last-named is preferably perforated. Assuming that these parts have been folded to produce th-e folder shown in Fig. 3 containing a stencil sheet Si! held by the interleaving heading lll, if it be desired to stencilize the stencil sheet, then the ap part is disengaged from the backing sheet and thereupon the fronting sheet and backing sheet may be opened and spread out in line as shown in Fig. 2, in which condition for the purpose of cutting the stencil the perforated end l5 can readily be inserted in the typewriter and through the manipulation of the platen roller of the typewriter in the usual way the stencil supported upon the backing sheet may be positioned as desired to carry out the stenciling operation, the fronting sheet during the stencilinfT operation trailing over the paper rest and behind the typewriting machine. Where it is not desired to perform a duplicating operation immediately after stencilizing the stencil paper, the parts for preserving and protecting the stencilised sheet may be folded up in folded condias illustrated in Fig. 3. Whenever, however, it is desired to perform a duplicating operation, the heading with the accompanying stencilized sheet is detached from the backing sheet along the perforated line l5. After the duplicating operation has been performed, the heading with the accompanying stencilized sheet may be disposed in their original position between the backing and fronting sheets, the folder closed and the flap part interlocked with the backing sheet when the entity structure may be hung up or stowed away in any suitable place until it is again desired to make use of the stencilized paper in a duplicating operation. An important advantage of my improved stencil sheet folder resides in the fact that the stencil sheet is preserved and protected against ruinpling or injury at all times, that the heading with the attached stencil sheet is readily detachable for the duplicating operation, and that after the duplicating operation the stencilized sheet can be preserved and protected for repeated use, and further that through provision of the space or surface El' on the exterior face of the fronting sheet, either by a notation or by an attached copy or reproduction of the stencilized matter, the stencil which is contained Within the folder may be fully identified.

As many changes could be made in the details of the above noted construction and many apparently Widely different embodiments of this invention could be made without departing from the spirit and scope thereof; it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
